There's nothing better than flying past heavy traffic. I used to love bombing through downtown Vancouver. Gotta watch out for the sudden lane changes, turns, and taxi doors, but that's kind of like the avalanches in skiing - objective hazard.

I also enjoy buzzing pedestrians who cross on red. Now I am in a university town and all of the students j-walk with their earbuds in so I try to see how close I can cut in front of them. If you try cutting behind, they will sometimes stop walking or take a step back which is no good for anyone.
